SUMMARY:Webinar: Assessing Capacity Accreditation Choice on Resource Mix Outcomes
DESCRIPTION:Genevieve de Mijolla\n\n\n\nDownload the Presentation \n\n\n\nWatch the Recording \n\n\n\n\n\n\n\nFeatured Speaker: Genevieve de Mijolla\, Technical Leader\, Electric Power Research Institute (EPRI) \n\n\n\nModerator: James Okullo\, Director of System Planning\, ESIG \n\n\n\nAbout the Webinar: A variety of capacity accreditation methods are used in power system planning\, but the implications of choosing one approach over another for capacity expansion decisions are not always well understood. This webinar explores how different approaches to accrediting wind capacity influence planning outcomes\, using an iterative workflow that links capacity expansion and resource adequacy modeling. By comparing several capacity accreditation methods\, the discussion highlights how methodological choices can lead to meaningfully different capacity values and investment signals. The analysis also illustrates why system-wide wind capacity values can overlook important spatial and temporal adequacy considerations\, and how closer alignment between planning and adequacy assessments\, such as through regional capacity values\, can improve decision-making. \n\n\n\nAbout the Speaker: Genevieve de Mijolla is a Technical Leader at EPRI where she leads the Resource Adequacy Assessments project set. She joined EPRI in 2021\, and has since contributed to a number of projects\, most notably to EPRI’s “Resource Adequacy for a Decarbonized Future” initiative. She is also the chair of the IEEE Resource Adequacy Working Group. Prior to joining EPRI\, she worked for GE Energy Consulting on production cost modeling and renewable integration projects. She holds a master’s degree in electrical engineering from the Rensselaer Polytechnic Institute. \n\n\n\nQ&A for the webinar will be hosted on Slido.

SUMMARY:Webinar: Grid-Forming Control for Power System Oscillation Damping: Insights from Angle Stability before the Iberian Blackout of 2025
DESCRIPTION:Dr. Lijun Cai\n\n\n\nDownload the Presentation \n\n\n\nWatch the Recording \n\n\n\n\n\n\n\nFeatured Speaker: Dr. Lijun Cai\, Professor and Chair of Electrical Power Systems\, University of Rostock \n\n\n\nModerator: Debbie Lew\, Executive Director\, ESIG \n\n\n\nWebinar Abstract: The rapid growth of inverter-based renewable generation is fundamentally changing power system dynamics and creating new challenges for system stability and secure operation. On April 28\, 2025\, the Spanish and Portuguese power systems were disconnected from continental Europe\, providing a critical real-world case for examining these challenges.This work combines system-level disturbance analysis with control-oriented studies to assess the role of grid-forming (GFM) renewable generation in providing effective damping to the system oscillations. The analysis of the Iberian power system prior to the blackout reveals increasing local and inter-area oscillations\, rising tie-line stress\, and reduced damping margins. In addition\, the generation performance following the blackout is investigated to evaluate system behavior under stressed and recovery conditions.Complementary studies on virtual synchronous generator (VSG) control demonstrate that GFM-controls actively participate in the oscillations and can provide stabilizing effects comparable to\, or even exceeding\, those of conventional synchronous generators\, particularly when traditional power system stabilizers (PSS) are unavailable.The results indicate that GFM control can serve as a practical and scalable stability resource for future power systems. For utilities\, the findings support integrating GFM-based damping services into grid codes\, operational planning\, and dynamic security assessment. Furthermore\, coordinated deployment of GFM control\, damping-oriented controller tuning\, and enhanced blackstart and restoration strategies are identified as key measures to ensure secure and resilient operation of future renewable-dominated power systems. \n\n\n\nAbout the Speaker: Since 2018\, Dr. Lijun Cai has been a Professor and Chair of Electrical Power Systems at the University of Rostock\, Germany. His current research interests include large-scale power system stability analysis and control\, renewable energy integration\, HVDC system design (LCC and VSC)\, and large-scale energy storage technologies. \n\n\n\nThe Q&A for this session will be hosted on Slido.
